Answer :
Final answer:
Dew point temperature is the point at which condensation occurs, indicating full saturation of air. Calculations based on vapor density at different temperatures help determine the dew point temperature.
Explanation:
Dew point temperature is the temperature at which condensation takes place when air reaches saturation, indicating 100% relative humidity. It's the temperature at which water starts to condense out of the air, and it varies based on the amount of moisture in the air.
For the given question, to determine the dew point temperature when the relative humidity is 39.0% at 20.0°C, specific calculations based on the saturation vapor density at different temperatures need to be made.
